Switching Mechanisms
SOR switching mechanisms are designed for use in harsh industrial atmospheres. SOR offers a
variety of electrical and pneumatic switching mechanism types to fit a wide range of applications.
The basic types of switch mechanisms available are listed below. See page 47 for specifications.
All SOR switching mechanisms are constructed from stainless steel and other durable
manufactured materials. Each mechanism is individually calibrated and inspected to insure
accuracy and repeatability. See below for the benefits and application of each switch type.
All mechanisms are interchangeable with most competitor units.
Standard Dry-Contact Switches
Types A, B, C, E
Standard dry-contact switches have open mechanisms and
exposed switching elements. These switching mechanisms are
easy to maintain. Visual confirmation of operation is obvious.
Dry-contact switch mechanisms are recommended for most level
switch applications and are available in SPDT and DPDT switch
arrangements.
Dry-Contact Switch Mechanisms feature:

High-load carrying capacity

High-quality phenolic insulator

Vibration resistance

Versatility of application
Mini-Hermetically Sealed Switches
Types L, S, T, V
Mini-hermetically sealed switches have a hermetically sealed
switch element on an exposed mechanism. Good for high-
temperature service and normal applications that require
hermetically sealed contacts.
Mini-Hermetically Sealed Switch Mechanisms feature:

Rugged stainless steel construction

Class I Group A rating for use in hazardous areas

Vibration resistance

High operating temperature limits
Anti-Vibration Switches
Types D and R
Anti-Vibration Switches employ two magnets to provide
vibration protection. Dual magnets prevent false trips by
providing a positive mechanical lock to the enclosing tube
when the switch is in any position.
(Type T switches are mini-hermetically sealed units with
dual magnets.)
